る特性を有することを特徴とする人工腎臓装置。 In an artificial kidney device that has an artificial kidney in which a permeable membrane is disposed between the dialysate and the blood, and that removes waste products from the blood through the permeable membrane, the flow rate of the dialysate into the artificial kidney and first and second positive displacement flowmeters that continuously measure the outflow amount in real time; and the ultrafiltration rate in the artificial kidney is adjusted by increasing or decreasing the fluid pressure of the dialysate or the fluid pressure of the blood in the artificial kidney. ultrafiltration rate variable means for changing the ultrafiltration rate; basic characteristic setting means for setting one ultrafiltration rate characteristic and total ultrafiltration rate among a plurality of types of ultrafiltration rate characteristics; The ultrafiltration rate is continuously calculated in real time from the measured value of the positive displacement flowmeter, and the calculated ultrafiltration rate always matches the change characteristic of the ultrafiltration rate set in the basic characteristic setting means. dialysis characteristic control means for controlling the ultrafiltration rate variable means so that at least one ultrafiltration rate among the plurality of types of ultrafiltration rate characteristics changes with time; Characteristic artificial kidney device.
